Pound Per Square Inch (abbreviations: psi, or lb/in2): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.
Kilopound Per Square Foot (abbreviations: ksf, or kips/ft2): is a British (Imperial) and American pressure unit which is directly related to the ksi pressure unit by a factor of 144 (1 sq ft = 12 in x 12 in = 144 sq in). Where, 1 kilopound per square foot equals 47.8803 kilopascals.
How to Convert Pounds Per Square Inches to Kilopounds Per Square Feet
Example: How many kilopounds per square feet are equivalent to 23.57 pounds per square inches?
As;
1 pounds per square inches = 0.14400009216006 kilopounds per square feet
23.57 pounds per square inches = Y kilopounds per square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 23.57 times 0.14400009216006 over 1
(i.e.) Y = 23.57 * 0.14400009216006 / 1 = 3.3940821722126 kilopounds per square feet
Answer is: 3.3940821722126 kilopounds per square feet are equivalent to 23.57 pounds per square inches.
